The ruins of Mshatta consist of a square enclosure, surrounded by an outer wall containing 25 towers. Its internal space is divided into three equal longitudinal strips, of which just the central one was completed to some degree. This central strip contains three major elements: on its southern side is what
K. A. C. Creswell called the "Gateway Block", followed by the large central courtyard, which leads northwards to the reception hall wing. The Gateway Block presents only the foundations of several rooms arranged symmetrically around a small courtyard. Among the rooms there is a small mosque, recognisable by the concave
mihrab on its southern wall, facing
Mecca. The large central courtyard had a rectangular pond at its centre. The reception hall wing, called by Creswell the "Main Building", placed at the centre of the northern part of the enclosure, was the only fully built section of the palace. It consists of a basilica-shaped hall (a vaulted hallway with three aisles separated by columns), leading up to the throne room. The throne room is
triconch-shaped (a "triple
iwan"), with the central conch once containing the throne, and was covered by a brick dome. The side rooms of the reception hall wing were combined into four residential suites, called in Arabic
buyut, the plural of
bayt,
barrel-vaulted and ventilated through concealed air ducts. in the
Pergamon Museum, Berlin The most famous element of Mshatta is the carved frieze which decorated a section of the southern facade, on both sides of the entrance gate. It is worth noticing that not the entire facade was adorned by the frieze, but only its central third, which corresponded to the very strip of the complex apparently reserved to the caliph, and the only one close to completion. The frieze is of high importance to scholars due to its original combination of Classical and
Sasanian decorative elements, thus being an early example of the east–west synthesis which led to the development of a full-fledged Islamic art. While much of the decorated part of the facade has been removed, the rest of the structure can still be visited
in situ, though little of what were probably once lavish decorative schemes remain. == Sculpture ==
